Question

Q92. Global-Scale Observations of the Limb and Disk instrument has been launched by:


  1. (a) ISRO

  2. (d) Russian Space Agency

  3. (b) NASA

  4. (c) European Space Agency


Solution

The correct option is C

(b) NASA


NASA’s Global-Scale Observations of the Limb and Disk (GOLD) instrument was recently launched atop an Ariane 5 rocket.

GOLD is essentially an imaging spectrograph. Spectrographs are scientific instruments that have been designed to break light down into its constituent wavelengths and to measure their intensity. By examining the data from such an instrument, scientists can determine a wide variety of characteristics, including a target’s composition and temperature. GOLD will be tasked with collecting far ultraviolet light data on Earth’s atmosphere.

Mission: To shed light on how the uppermost layers of Earth’s atmosphere can be affected by powerful space and Earth-based weather events.
